The paper presents a simple and cost effective solution to supply high side power electronic switch gate drivers. The solution can be integrated and it is demonstrated that it can be loss free, depending on how the power switch is driven. The solution is based on a pulsed linear regulator, only sensitive to a positive dv/dt. At every main power switch's turn OFF, it recycles the switching losses in order to recharge a storage capacitor. The paper presents the global operation and focuses on… CONTINUE READING
